melting. Urine samples were taken from participant who agreed to
participate in the present study. The concentrations of heavy metals
(Cadmium, Copper and Nickel) were analyzed by atomic absorption
spectrophotometer (AAS).
Findings: the study included 47 male workers with average age of 31.7
years. The concentrations of Cadmium, Copper and Nickel were higher in
study participants compared with control participants. Exposure to Cadmium
was significantly higher among workers compared with control (12.65 µg/l,
4.66 µg/l; P 0.001). Exposure to both Nickel and Copper was not statistically
significant (P > 0.05).
Conclusion: workers in jewelry are exposed to heavy metals Cadmium,
Copper and Nickel and Cadmium exposure is more apparent. Exposure to
Copper and Nickel seems to have other routes as indicated by control group.
